How to test your home for radon - Short-term testing is recommended for a first-time test. If the result of your first test was below 2.0 pCi/L, no further action is required. For test results between 2.0 pCi/L and 8.0 pCi/L you should conduct either a short-term (three to seven days) or a long-term follow-up measurement (ninety days to one year) before making a mitigation decision. Due to the additional health risks associated with very high radon concentrations, a short-term follow-up measurement is recommended when your first test is over 8.0 pCi/L

​When testing your home for radon be sure to carefully follow the test device instructions. The following EPA radon testing protocols must also be followed for accurate radon measurement:

Test the lowest livable and frequently occupied level of your home.

All windows and exterior doors must be closed at least twelve hours before starting your test and during the entire test device exposure. (Other than normal entry and exit)

Place the test device where it will not be disturbed and in the normal breathing zone. (Three to six feet from the floor)

Do not place the test device in a draft or near exterior windows and doors.

Avoid testing near heat sources and areas with high humidity like kitchens and bathrooms.

Return your test sample to the lab immediately after competing the test exposure.

Important - Failure to follow test device instructions will invalidate your test. Please contact us if you have any questions about your radon test device, radon measurement protocol or the lab analysis report.
